  Thinking About Where To Go From Here, Besides to Lunch

We can envision a number of different scenarios for our involvement with the high school Math Department. For example, suppose we serve as a provider of demos and materials for specifically requested content.

We could provide technology-supported investigations in a PoW environment, driving the benefit of our interactions directly to students. Teachers could be involved in generating the problems, mentoring or defining guidelines for the mentoring, and examine student work as a vehicle for professional development targeted on practice and/or curriculum development.

We can provide continuing support in both face-to-face and on-line conversations.
